BASEPRI and Task Priority for Cortex-M4

The user guide shows a table of values for task priorities 0-7. The "writing your first MQX application" document suggests that any task defined by the application should not be between 0-8.


What is BASEPRI for tasks above 8?


What is the range of values for priorities? What is the highest numerical value?


A queue is created for each priority so I understand that it will increase memory but is this done dynamically or statically (by a configuration constant)?


I chose to define a single spawn task in the task template. My other tasks are created dynamically.
